    摘要: The invention is intended to provide a mass flow control device incorporating a verification tank, in which the mass flow testing operations are conducted by the device itself. A mass flow control device comprises control means 18 for controlling a flow control valve mechanism based on an externally input flow set signal and a flow signal. The mass flow control device is equipped with a mass flow detector means 8 and a flow control valve mechanism 10 both of which are set in a channel 6 through which a fluid flows. The mass flow detector means 8 detects the mass flow of the fluid that flows through the channel and outputs the flow signal. The flow control valve mechanism 10 controls the mass flow by altering the valve aperture by means of valve drive signals. The mass flow control device is also equipped with a verification valve 42, a verification tank 44 and pressure detector means 46 in the channel. The verification valve 42 opens and closes the channel. The verification tank 44 has a certain volume. The pressure detector means 46 detects the pressure of the fluid and outputs pressure detection signals. The mass flow control device is also equipped with verification control means 48 which controls the detection valve and detection tank and pressure detector means to carry out the mass flow testing operations.

    摘要: When a connection is made between a first communication device and a second communication device at a first connector and a second connector, information is generated and exchanged for the purpose of specifying parties to mutual wireless communication. After this information exchange, information is added by a transceiver to data transmitted and received by wireless communication for the purpose of identifying the party to the communication and, by setting the first communication device and the second communication device so that they respond only to data having that data added thereto, one-to-one communication between the first communication device and the second communication device is achieved. One-to-many communication between a first communication device and many second communication devices is also provided.

    摘要: A multiple-frequency common antenna has a first substrate sheet and a second substrate sheet respectively structured by an HIP consisting of a metal plate, small metal plates disposed in two dimensions and linear metal bars connecting these elements. The antenna restricts propagation of surface currents of the first and second frequency bands which are not overlapping with each other. An inverse L-shape antenna and a monopole antenna which are fed with a center conductor and an external conductor of the coaxial line respectively operate as the antenna on the first substrate sheet in the first frequency band and second frequency band. The second substrate sheet does not propagate the radiated wave of the monopole antenna, thereby avoiding unwanted re-radiation.
